Abstract:
An automated ignition assembly for a gas-fueled appliance includes a pressure plate positioned between an upper bellows and a lower bellows, each of which is in selective communication with a fuel gas source. If fuel gas is directed to the lower bellows, gas within the upper bellows is diverted to an ignition site; as the lower bellows inflates, it lifts the pressure plate and an associated linkage assembly to engage a piezo igniter, which creates a spark at the ignition site. The lower bellows is then deflated and the upper bellows is inflated to again engage the piezo igniter. Once a flame has been generated, or if a flame has not been generated within a predetermined time period, an automated valve disables fuel gas flow to the bellows.
